Mini greenhouse pet bottle to emerge aquarium plants

The emersed cultivation can be interesting both in itself and as a way of spreading aid to the aquarium, as some plants have a much faster emersed growth, in addition to being safer and cheaper cultivation way, since there are no problems with algae do not need filtration system nor heating, so when there is a desirable amount of the plant, you can pass it to the aquarium, preferably with a period of adaptation to the aquatic environment.
The only requirements are emersed cultivation lighting, humidity and always keep a well-soaked substrate.

Well, here's a tip construction of a mini greenhouse made from plastic bottles, which can be used to adapt plants to emersed cultivation.

Material for making the greenhouse:

Two bottles of 2L soda (Transparent)
Tosoura
Drill 3mm (if you are using drill or Dremel, otherwise use a nail)
acrylic wool

Sobstrato:

Earthworm Humus
Garden sand
xaxim powder (optional)

Way of doing:

1st step: Cut the bottom of the bottle, as shown below:

The bottle should look like this:

2nd step: Drill holes in the second bottle with a drill of 3mm hot nail, or what you have right now.

It should be well spaced, about 10 holes are already enough:

Step 3: Cut the top of the bottle you made the holes:

You will get two pieces:

Step 4: Plug the mouth of the bottle which you removed the background, with acrylic wool:

Step 5: Fill the bottom of the second bottle with water up to half the height
